Recently, the Xiao Wansheng team of the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, in collaboration with researchers from the Institute of High Energy Physics of the Chinese Academy of Sciences, the Institute of Fluid Physics of the China Academy of Engineering Physics and the Institute of Geophysics of the Carnegie Institute of the United States, used diamond pressure chambers. A high-pressure device was used to perform high-pressure in-situ X-ray diffraction on a high-temperature and high-pressure treated PbGeO3 sample on a Beijing Synchrotron Radiation Facility (BSRF). A new PbGeO3 cubic perovskite high phase (Phase II) was discovered.

The combination of diamond-based anvil ultra-high pressure technology and synchrotron radiation X-ray diffraction technology is one of the most important methods to study the structural changes of materials under high pressure. In this work, PbCrO3 cubic perovskite pressure-induced structural phase transitions lead to abnormally large volume changes and its peculiar physical mechanism, which poses new challenges to the traditional perovskite phase transition theory research, opening a new class of The door to high-pressure behavioral studies of perovskite structures will have an important impact on solid physics, chemistry, materials science, and earth science.
